Description

Technical Field

[0001] The utility model relates to the technical field of threaded shaft sleeve processing, in particular to a positioning fixture for threaded shaft sleeve processing. Background Art

[0002] A threaded sleeve is an accessory that is sleeved outside a shaft, generally sleeved outside a bearing. Threaded sleeves can be divided into plastic and steel according to the material. For plastic threaded sleeves, the existing processing of the threaded sleeve is generally completed in two steps. First, the sleeve base is processed by pressing and then the threads are processed at the specified position on the sleeve base. The working process of the existing pressing mold for the threaded sleeve is: the plastic raw material (such as phenolic plastic) is placed in the mold cavity, and then the lower protrusion of the upper mold plate is extended into the groove of the lower mold plate to complete the mold closing. After the mold closing, the upper and lower mold plate assembly is placed between the workbench and the upper platen of the press, and the upper platen is lowered to press the upper mold down.

[0003] Although the positioning fixtures currently in use can clamp workpieces, they are unable to unify the placement of the workpieces. That is, after clamping, some workpieces are tilted or not placed in place. The processing equipment used in conjunction with the positioning fixtures cannot adapt to these randomly placed workpieces. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A positioning fixture for processing a threaded sleeve includes a clamping mechanism and a power mechanism, the clamping mechanism includes two clamping blocks, two pressure wheels movably embedded in the inner sides of the clamping blocks, a push plate movably arranged between the two clamping blocks, two pressure wheels movably connected to the push plates, and a power mechanism, the power mechanism includes a base plate connected between the two clamping blocks, two guide rods connected to the bottom of the base plate, a mounting seat slidably connected between the two guide rods, two cross rods sliding through the mounting seat, a cylinder connected between the base plate and the mounting seat, and the push plate is sleeved on the outside of the two cross rods.

[0007] By adopting the above technical solution, the threaded sleeve is placed on the top of multiple universal balls, and then the cylinder is started. The movable end of the cylinder pushes the mounting seat to move, and the push plate, the second pressure wheel, and the cross bar follow the movement. Then the two second pressure wheels contact and push the threaded sleeve, so that the threaded sleeve enters between the two clamping blocks. Here, in order to ensure complete contact between the first and second pressure wheels, the threaded sleeve will rotate on the universal ball and adjust its direction. Then, when the first and second pressure wheels clamp the threaded sleeve, the threaded sleeve is placed on the plate straight, which is convenient for external processing equipment to process.

The movable end of the cylinder pushes the mounting seat to move, and the push plate, the second pressure wheel, and the cross bar follow the movement. Then the two second pressure wheels contact and push the threaded sleeve, so that the threaded sleeve enters between the two tightening blocks. Here, in order to ensure that the threaded sleeve fully contacts the first pressure wheel and the second pressure wheel, it will rotate on the universal ball and adjust its direction. Then, when the first pressure wheel and the second pressure wheel clamp the threaded sleeve, the threaded sleeve is placed on the plate straight, which is convenient for external processing devices to process.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0024] A positioning fixture for machining a threaded sleeve provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0025] Example 1:

[0026] Combine Figure 1-3 As shown, the present invention provides a positioning fixture for threaded sleeve processing, including a clamping mechanism 100 and a power mechanism 200. The clamping mechanism 100 includes two abutting blocks 110, two pressure wheels 120 movably embedded inside the abutting blocks 110, a push plate 130 movably arranged between the two abutting blocks 110, and two pressure wheels 140 movably connected to the push plate 130.

[0027] The power mechanism 200 includes a base plate 210 connected between the two clamping blocks 110, two guide rods 220 connected to the bottom of the base plate 210, a mounting seat 230 slidably connected between the two guide rods 220, two cross bars 240 sliding through the mounting seat 230, and a cylinder 250 connected between the base plate 210 and the mounting seat 230. The push plate 130 is sleeved on the outside of the two cross bars 240.

[0028] Furthermore, the two guide rods 220 are respectively close to the front and rear sides of the base plate 210. Both ends of the guide rods 220 are set to be "﹁" shaped, and the bending part is set in an arc shape. With this shape design, the main body of the guide rod 220 can be suspended on the top of the base plate 210, ensuring that the mounting seat 230 can be smoothly put on the outside of the guide rod 220.

[0029] Furthermore, the mounting seat 230 is suspended on the top of the base plate 210 and is made of metal material. The mounting seat 230 made of metal material can stably move with the cross bar 240 and the push plate 130.

[0030] Example 2:

[0031] Combine Figure 1 and Figure 3 As shown, based on the first embodiment, the cross bar 240 is made of the same material as the guide bar 220. Using the same metal material can reduce the difficulty of material selection when manufacturing the cross bar 240 and the guide bar 220.

[0032] Example 3:

[0033] Combine Figure 1 and Figure 3 As shown, in the above embodiment, a plurality of universal balls 300 are movably embedded in the top of the base plate 210 , and the plurality of universal balls 300 are arranged at equal intervals and in a matrix. The provision of the universal balls 300 can facilitate translation of the threaded sleeve.

[0034] Furthermore, a plurality of universal balls 300 arranged in a matrix are located between the two guide rods 220 . The universal balls 300 are made of stainless steel. This layout design does not affect the installation of the guide rods 220 and facilitates the movement of the threaded sleeve.

[0035] The working principle and use process of the present invention are as follows: when the device is put into actual use, the threaded sleeve is placed on the top of multiple universal balls 300, and then the cylinder 250 is started, and then the movable end of the cylinder 250 pushes the mounting seat 230 to move, and the push plate 130, the pressure wheel 2 140, and the cross bar 240 follow the movement, and then the two pressure wheels 140 contact and push the threaded sleeve, so that the threaded sleeve enters between the two tightening blocks 110, here, the threaded sleeve is to ensure full contact with the pressure wheel 1 120 and the pressure wheel 2 140, and it will rotate on the universal ball 300 and adjust the direction, and then when the pressure wheel 1 120 and the pressure wheel 2 140 clamp the threaded sleeve, the threaded sleeve is placed on the plate straight, which can facilitate processing by external processing devices.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
